The dialis a jog dial that receives a rotation operation by the driver H. The push buttonsare button switches that receive a push operation by the driver H.

412 411 411 412 The push buttonsare located adjacent to the dial. Therefore, the driver H can easily perform the rotation operation of the dialand the operations of the push buttonsperformed in association with the rotation operation.

412 411 412 411 41 411 412 The push buttonsare located side by side on the right side of the dial. In the case of the present example embodiment, three push buttonsare located side by side in the front-rear direction adjacent to the dial, for example. When the driver H operates the rotation manual controllerwith his/her right hand, the dialcan be operated with the thumb and the index finger, and the push buttonscan be operated with the middle finger or the ring finger, so that the movement of his/her hand can be reduced.

41 41 50 22 An example of a function of the rotation manual controllerwill be described. The rotation manual controlleris used to change the display of the display deviceand also has a function of performing an operation of adjusting the rotation speed of the drive assembly.

411 22 50 22 10 17 14 16 When the driver H rotates the dialclockwise, the controller increases the rotation speed of the drive assemblyaccording to the amount (rotation angle) of the rotation operation. In accordance with this rotation operation, information on the rotation speed is displayed on the display device, and the driver H can confirm the rotation speed. The rotation speed of the drive assemblyaffects the traveling speed of the work vehicle, the rotation speed of the PTO shaft, or the operation speed of the work devicesand.

22 50 411 411 In the case of the present example embodiment, a frequently used rotation speed (for example, the idling rotational speed or the maximum rotational speed) among the rotation speeds of the drive assemblyis set in the controller in advance as a default value. The display devicedisplays the plurality of default values side by side. One default value of the plurality of default values is displayed as a selection candidate (for example, displayed in a thick frame), and the default values displayed as the selection candidate (for example, displayed in a thick frame) are sequentially switched by rotating the dial. That is, the dialis used to select one default value from the plurality of default values.

411 22 In a state where one default value is selected, one default value can be determined by pressing the dialalso having a function as a push button. When one default value is determined, the controller is configured or programmed to perform control to match the rotation speed of the drive assemblywith the determined default value.

412 412 412 412 413 412 412 50 413 50 In the case of the present example embodiment, three push buttonsare provided, for example. The three push buttons(A,B,C) are positioned side by side from a side far from the driver H toward a side close to the driver H (from front to rear), and different functions are assigned to the push buttons. The first push buttonA has a preset function such as calling preset information. The second push buttonB has a function of switching between the home screen and the function screen in the display device. The third push buttonC has a function of returning to the previous screen in the display device.

41 Note that such functions of the rotation manual controllerare examples, and can be used for various purposes.

An accelerator pedalis provided on the driving flooras an operation pedal that can be operated by the foot of the driver H sitting on the driver's seat(see). The operation of the accelerator pedalactivates the work vehicleand changes the traveling speed of the work vehicle.

42 48 49 42 42 10 10 42 The cruise leveris connected, via a power transmission, to a movable mechanism unit (not illustrated) linked with the accelerator pedal. When the driver H performs a pulling-up operation, the cruise leveris held as it is. When the cruise leveris pulled up, the state of the movable mechanism unit is maintained, and the traveling speed of the work vehicleis kept constant. As a result, the work vehiclecan travel at a constant speed without the driver H continuously stepping on the accelerator pedal. As described above, the cruise leveris a lever type switch to control the traveling speed.

43 22 43 22 22 22 10 The on/off manual controlleris an ignition key, and functions as a switch (key switch) to control on/off of the drive assembly. By rotating the on/off manual controllerin the first direction, the drive assemblyis turned on. In a case where the drive assemblyincludes a motor, when being turned on, the drive assemblyenters a standby state in which a drive current can flow through the motor. Thereafter, the motor is rotationally driven according to the operation of the accelerator pedal, and the traveling of the work vehicleis started.

43 22 When the on/off manual controlleris rotated in the second direction opposite to the first direction, the drive assemblyis turned off. In the off state, the vehicle is in a stop state in which the drive current cannot flow to the motor.

44 37 44 37 38 37 44 37 38 The tilt leverwill be described. As described above, the position of the handlecan be changed by the tilt mechanism. By moving the tilt leverin the first direction, the handleand the steering shaftare brought into a free movable state in the tilt mechanism. The handleis adjusted to a desired position in the free state. When the tilt leveris moved in the second direction opposite to the first direction, the handleand the steering shaftare not movable in the tilt mechanism.

45 10 45 45 The combination switchincludes a plurality of push button switches. Although not illustrated, the work vehicleincludes a direction indicator, an emergency blinking light, and a headlight.

46 10 17 10 31 17 31 17 10 46 17 17 17 11 The stationary PTO switchwill be described. As described above, the work vehicleincludes the PTO shaft. The work vehicleis configured such that a sensor is provided on the driver's seat, and the PTO shaftdoes not rotate unless the driver H sits on the driver's seat. Exceptionally, it may be necessary to rotate the PTO shaftin a state where the driver H stands beside the work vehicle, for example. At this time, when the stationary PTO switchis operated, the PTO shaftis exceptionally rotatable, that is, the rotation of the PTO shaftis exceptionally permitted. Note that a changeover switch for rotation and stop (on and off) of the PTO shaftis provided in the vehicle main body(fender).

40 The arrangement of the plurality of manual controllerswill be described.

4 FIG. 40 10 33 39 33 50 33 41 33 33 31 33 40 50 41 33 As illustrated in, the manual controllerincluded in the work vehicleof the present example embodiment includes the operation panelfacing the driver H, the steering postextending from the operation paneltoward the driver H, the display deviceprovided on the operation panel, and the rotation manual controllerprovided on the operation paneland operable by the driver H. The operation panelfaces the driver H sitting on the driver's seatand facing the front, and is located in front of the driver H. The operation panelis provided with the plurality of manual controllersincluding the display deviceand the rotation manual controller. Therefore, the operability of the operation panelis high.

39 31 50 41 39 The steering postis located closer to the driver H (driver's seatside) than the display device. The rotation manual controlleris located on the right side which is one side of the steering postin the left-right direction.

In a case where an intersection between the upper surface of the operation panel(second surface) and the center line of the steering postis set as a reference Q and a two-dimensional coordinate system is set on a plane including the upper surface, the rotation manual controlleris located farther from the reference Q than the on/off manual controller. That is, the rotation manual controlleris located farther from the steering postthan the on/off manual controller.

4 FIG. 41 1 371 37 333 33 41 1 333 33 1 1 333 33 2 41 1 2 33 As illustrated in, at least a portion of the rotation manual controlleris located between a virtual vertical plane Kpassing through a right endof the handleand spreading in the front-rear direction and a right endof the operation panel. In the case of the present example embodiment, a right half or more of the rotation manual controlleris located between the virtual vertical plane Kand the right endof the operation panel. Assuming that the virtual vertical plane Kis a “first virtual vertical plane K” and a virtual vertical plane that passes through the rightmost endof the operation paneland spreads in the front-rear direction is a “second virtual vertical plane K”, at least a portion of the rotation manual controlleris located between the first virtual vertical plane Kand the second virtual vertical plane Kon the operation panel.

41 1 1 33 332 33 1 1 4 FIG. 4 FIG. The rotation manual controlleris provided across an intersection line Lbetween the first virtual vertical plane Kand the operation panel(second surface). Sinceis a view of the operation panelas viewed from the driver H side, that is, as viewed in plan view, the first virtual vertical plane Kcoincides with the intersection line Las illustrated in.

41 1 The rotation manual controlleris provided in a range within the width dimension of the palm, specifically, within about 20 cm from the intersection line Lto the right, for example.

411 41 1 In the case of the present example embodiment, the dialincluded in the rotation manual controlleris located at a position overlapping the intersection line L.

41 41 1 1 33 332 4 FIG. Alternatively, the rotation manual controllermay be located on the right side of the configuration illustrated in. That is, the entire rotation manual controllermay be provided in a region on the right side of the intersection line Lbetween the first virtual vertical plane Kand the operation panel(second surface).

37 Normally, the driver H often grips the handleto operate the work vehicle.

41 41 37 41 Therefore, according to the position of the rotation manual controlleras described above, the driver H can operate the rotation manual controllerby lowering his/her hand (right hand) from the handle. The operability of the rotation manual controlleris good.

41 50 41 50 As described above, the rotation manual controlleris used to change the display on the display device. Therefore, the driver H can operate the rotation manual controllerwhile checking the display content of the display device, and can easily perform the operation.

40 33 41 42 43 33 39 33 41 42 43 39 The plurality of manual controllersis provided on the operation panel. The rotation manual controller, the cruise lever, and the on/off manual controllerare located in a right-half region of the operation panel. The steering postis located at the center of the operation panelin the left-right direction. The rotation manual controller, the cruise lever, and the on/off manual controllerare located in a region on the right side of the steering post.

33 41 42 41 40 33 40 In the right-half region of the operation panel, the rotation manual controllerand the cruise leverare located on the outermost side (right outer side) in the left-right direction. That is, the rotation manual controlleris one of the manual controllerslocated on the outermost side (in the case of the present example embodiment, the right outer side) in the left-right direction on the operation panelamong the plurality of manual controllers.

41 42 43 41 41 40 37 The rotation manual controlleris operated more frequently than the cruise leverand the on/off manual controllerlocated on the same right side. Since the rotation manual controlleris located on the outer side (right outer side) in the left-right direction, the operation of the rotation manual controlleris less likely to be disturbed by the other manual controllersor operation devices (for example, the handle).

3 FIG. 33 331 50 332 331 41 332 331 332 41 50 As described with reference to, the operation panelincludes the first surfaceon which the display deviceis provided and the second surfacelocated closer to the driver H than the first surface. The rotation manual controlleris provided on the second surface. Regarding the inclination angle θ using the horizontal plane P as a reference, the first surfacehas a larger inclination angle than the second surface(θ1>θ2). Thus, the driver H can operate the rotation manual controllerwith his/her right hand relaxed while visually recognizing the display device.

41 50 50 31 50 41 41 50 The rotation manual controlleris located on the right side of the display deviceand closer to the driver H than the display device, that is, on the driver's seatside. The driver H can easily check both the display deviceand the rotation manual controller. The driver H can easily operate the rotation manual controllerwhile visually recognizing the display device.
